Bio

My research sits at the interface of plant microbiomes, host genetics, and immunity. I use quantitiative genetics and reverse genetic approaches to better understand how plant host modulate their root microbiomes, how microbiota impact plant growth, and how the plant immune system affects and is affected by microbiota.
